Title: Agitative/oscillatory device for reclamation of oil-containing material
Inventor: IWASE MASANORI
IPC: B01D3/00
Filed: 1989-01-20
Abstract: PURPOSE:To shorten the treating time and to save thermal energy by agitating and/or oscillating an oil-containing material in a process for separating and recovering oil and inorganic substances from an oil-containing powder of various inorganic substances. CONSTITUTION:An oil-containing powder of various inorganic substances (e.g. an iron powder containing lubricating oil, generated due to the abrasion of rolling-mill bearings) is, for example, put into a heating chamber 4 through a charge port 1 and dispersed throughout the interior of the chamber 4 with rotating blades 6 attached to a combustion tube 3 which rotates with a drive unit 8. The temperature in the chamber 4 is raised by means of a combustion furnace 9, a heating burner 10, and rotating heat exchange blades 5. When the temperature of the oil-containing material reaches 400-500 deg.C, the oil evaporates. The evaporated oil is liquefied in a liquefying tube and collected in an oil collecting chamber 11. Part of the liquefied oil is sent to the heating burner 10. On the other hand, the inorganic substance from which oil has been evaporated is recovered through an outlet 16. Thus the combustion tube 3 is rotated with the drive unit 8 so that an oil-containing material is agitated and/or oscillated by means of the rotating heat exchange blades 5 and rotating blades 6 both attached to the combustion tube 3 to thereby realize efficient reclamation of the oil-containing material.

Title: Method for estimating life of superheater pipe for boiler
Inventor: TOMONO YUTAKA
IPC: G01N33/20
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To easily determine a life considering intergrannular corrosion. SOLUTION: Two, first test pieces consisting of carbon steel and two, second test pieces consisting of the same material as a superheater pipe A are prepared. The first and the second test pieces are mounted to the upstream and downstream sides in the flow direction of the combustion gas of the superheater. After a boiler operates and a specific period passes, the hardness of all first test pieces is measured and a tempering parameter after the specific period of each first test piece passes based on a known relationship between the hardness due to tempering and the tempering parameter.  Also, the amount of corrosion of each second test piece is measured, the relationship between the tempering parameter of each first test piece and the amount of corrosion of the second test piece being mounted to the same part as the first test piece is drawn in a graph, and the tempering parameter of the first test piece corresponding to the amount of limitation corrosion of the superheater is obtained based on the graph. The life of the superheater is calculated from the tempering parameter.

Title: Magnetic recording medium and its production
Inventor: KOKADO YUICHI
IPC: G11B5/73
Filed: 1987-01-23
Abstract: PURPOSE:To prevent deterioration of lubricity by preservation in a high-humidity atmosphere and to obtain long-term stability by forming a thin amorphous carbon film on the surface of a substrate, then removing the part from the surface down to a prescribed depth. CONSTITUTION:The thin amorphous carbon film is obtd. by using an org. compd. such as CnHm (n, m are integers) as a raw material and depositing said compd. while bmbaring the same with high-energy ions to form a dense carbon-carbon bond. However, the compd. is deposited on the part near the surface during the stop of the reaction or just before said stop and, therefore, the sufficiently dense bonds are not formed and said part has the many unstable bonds which are approximate to an org. material. Deterioration with lapse of time is, consequently, liable to arise in said part and leads to the deterioration in the protective film characteristics with lapse of time. The unstable part of the thin amorphous carbon film is removed by using a dry process etching method, by which the part having the stable bonds is brought to the surface and, therefore, the deterioration with lapse of time is lessened.

Filed: 1993-01-28
Abstract: PURPOSE:To reduce a cost of laser light source and to simplify a laser driving circuit by collecting the light emitted from a linear polarization light source by a condenser lens, irradiating the surface of a magnetic recording medium, and recording information. CONSTITUTION:The s polarization parallely separated by a BDP 9 passing through a 1/2 wavelength plate 10 is reflected by a magneto-optical disk 4. A light receiving element 11b is arranged on the L light path as the 1st light path passing the BDP9 without through the 1/2 wavelength plate 10. In the conventional case, the 1/3 P polarization is reflected by a beam splitter to cause the loss of light amount as it does not reach the magneto-optical disk. In the BDP9, all the light can be used for recording. Thus, a semiconductor laser with the lower power of 2/3 of the conventional one can be used.

Filed: 1984-01-30
Abstract: PURPOSE:To take up strips formed of piled pieces divided in lateral direction tight to the reel cores by winding each strip around each reel core fixed around the same take-up axis and pressed in the axial direction with torque transfer plates. CONSTITUTION:Reel cores 14 fixed around a common take-up axis 12 are pressed in the axial direction by the torque transfer plates 16 placed closely in between the adjacent reel cores 14 and on the outsides of the two reel cores 14 located at both ends. Each reel core 14 is pressed by a common pressing roller 20 giving pressure on to the axis 12 through the wound strips 2. The pressure of the roller 20 is set greater than the frictional force between reel cores 14 and torque transfer plates 16; the take-up diameter of each reel core 14 is kept at the same level by the roller 20; the take-up velocity depends on the product of the take-up diameter and the angular velocity of the axis 12 irrespective of the thickness of any strips 1. Therefore, each coil will not be loosened.
